Application led December 9, 1915. Serial/No. 66,002.

To au whom it may concern:

Be it known that' I, HENRY H. DUPONT, a citizen of the United States of America, residing at St. Petersburg, in the county of Pinellas and State of Florida, have invented certain new and useful Improvements in Roofing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsfto make and use the same.

This invention relates to a roofing construction in which shingles made of plastic materia-l are used in conjunction with a novel cotta tile roofing. l

This is the primary object and purpose of my invention while subsidiary to the main object are other objects and purposes consisting in a, novel method of forming the substructure laying the plastic shingles so that alternate gutters and ridges are formed, the ridges shedding water into the gutters and the gutters carrying it to the eaves of the roof, the shingles being so laid and overlapped that double protection is secured against any passage of water through the shingles'.

To these ends I have devised a roofing constructed as shown in the accompanying drawing, in which;

Figure l is an elevation of a fragment of a roof made in accordance with my invention. Fig. 2 is an enlarged transverse section taken through the roofing; and Fig. 3 is a sectional view illustrating the method of sawing lumber to form the elements of the substructure upon which -the shingles are laid.

Like reference characters refer to like parts throughout the several views of the drawing.

In the construction of a roof in accordance with my invention a plurality of strips 1 are laid in parallel relation reaching from the eaves of a roof tothe peak thereof. These strips may be supported by any suitable form or type of rafter or other support. Covering the space between an adjacent pair of strips is a member 2, the cross section of which is shown as a trapezoid, the longer base of which covers the space between an adjacent pair of strips 1 and partially overlaps each strip. I prefer to form-the members 2 from a plank which may be sawed substructure to form an imitation of terra-.

upon the lines a and b, in this manner making a member 2 and at the same time two members 3, each of which in cross section is,

equal to one-half of the cross section of a member 2. By placing two of these members 3 .together with the kouter edges as shown `in Fig. 3 in contact as illustrated in Fig. 2 and securing them-together in any suitable manner an additional member Vsimilar in all respects tothe member 2 is formed, and this is laid upon and covers the space between an adjoining pair of strips 1. Then the substructure for the roof is finally complete a plurality of strips 1 in spaced apart relation are located between the peak and eaves of aroof and the spaces between said strips are alternately covered by a member 2 while the intermediate spaces are covered by another member formed of the'two parts 3 which when secured permanently together are equivalent toa member 2 in every respect. A substructure thus formed has alternate ridges and valleys and in the valleys lplastic shingles 4 are laid beginning at the eaves in the usual manner in laying shingles and working toward the peak of the roof, it being apparent that each shingle laps a distance over the shingle next below.

Shingles 4 may be of any suitable plastic formation and the usual and well konwn asphalt shingle, preferably, will be used, said shingle having the plastic property which permits it to be bent into various shapes without injury. It will be noted that the edges of said shingles 4 extend a distance up the inclines of the raises formed by members 2 and 3. After the gutters are thusformed shingles 5 are laid over the members 2 and 3, their edges passing over and overlapping the edges of the shingles 4. Shingles 5 are laid beginning at the eaves of a roof and progressing toward the peak and in a similar manner shingles 5 overlap each other the same as do the shingles 4.

With a roof thus constructed alternate ridges and gutters are formed from one side of the roof to the other and extend from the peak to the eaves of the roof. This produces a roof which looks very like the usual terracotta tile roof, it of course being understood that the shingles 4 and 5 may be suitably colored for this purpose. Water which falls upon the roof will run down into the gutters passing over the shingles 5 on to shingles 4 and will be thence carried down the shingles tito the eaves. It is 4apparent that by 2 reason ofthe manner in which the shingles are laid no water can get underneath the shinglesor vpass between them in any way so as to reach the substructure on which the j shingles are laid to pass therethrough. `An

roof, members'each having a comparatively widebase coveringthe space between adjacent strips, said-members inclining upwardly from said base, flexible shingles laid in the guttersbetween said members and extending partially over adjacent inclined sides of adjacent members, each shingle being partially gGopies of this patent may be obtained for overlapped by the shingle neXt above, and flexible shingles similarly laid on said members and overlapping the side edges of the shingles'laid in the adjacent gutters, substantially as described.

2; In a roofing construction, a substructure including parallel spaced strips extending upwardly from the eaves of the roof, ridge members formed with a wide base, narrower top and inclined sides positioned to cover the spaces between said strips, thereby forming parallel ridges with gutters of inverted similar cross section between, roofing material laid lengthwise of the gutters and roofing material laid lengthwise of the ridges overlapping onto the material laid in said gutters. 1

In testimony whereof I aiIiX my signature.

HENRY H. DUPONT.
